London -LRB- CNN -RRB- -- Portuguese coach Andre Villas-Boas was confirmed as the new manager of Chelsea Wednesday .

The 33-year-old will become the youngest manager in the English Premier League .

He moved to the west London giants after a payment of $ 15 million -LRB- $ 21.6 million -RRB- made to his former club Porto triggered a release clause in his contract .

Villas-Boas , who guided Porto to a treble last season , has signed a three-year contract at Stamford Bridge and will replace Italian coach Carlo Ancelotti , who was sacked in May .

`` Chelsea football club is delighted to announce that Andre Villas-Boas will be the club 's new manager , '' read a statement on the team 's official website .

Could Villas-Boas succeed at Chelsea ?

`` His ambition , drive and determination matches that of Chelsea and we are confident Andre 's leadership of the team will result in greater successes in major domestic and European competitions . ''

The former Academica coach worked as a scout for the four-time English champions under compatriot Jose Mourinho , who is now in charge of Real Madrid .

Mourinho -- like Villas-Boas -- guided Porto to a trio of domestic and European honors in 2003 , before winning two Premier League titles , one FA Cup and two League Cups as Chelsea boss between 2004 and 2007 .

Is Villas-Boas the new ` Special One ' ?

Turkey head coach Guus Hiddink had been linked with the vacant position after he enjoyed a successful temporary spell with Chelsea in 2009 , but billionaire owner Roman Abramovich has opted for Villas-Boas .

Former AC Milan coach Ancelotti was dismissed after a trophy-less campaign saw Chelsea finish second in England 's top division , despite delivering a league and FA Cup double the previous year .

Abramovich will hope Villas-Boas can secure Chelsea the European Champions League , an honor which has so far eluded the Russian since he gained control of the club in 2003 .

Meanwhile , seven-time French champions Lyon announced the appointment Wednesday of Remi Garde as their new manager .

The former French international has been in charge of the club 's youth set-up and replaces Claude Puel , who left Monday with a year left on his contract .

Garde was capped six times by his country and played for Lyon for nine years before moving on to Strasbourg and Arsenal in the English Premier League .
